So am going to start gearing up to make a deck with built in batteries and esc. Want to build the batteries into the board so I can keep my set up nice and low how I like it.



The plan is to make the deck load batteries kind of like an rc car/mag lite, where I can take the batteries out individually.

The reason I want to do this is so that I can take all the batteries out of my deck, and replace the (soon to be) hubmotors with normal thane and ride the board like a normal deck. Keen to the thought of having one tool/toy that does it all, and still quite enjoy pushing around and pumping. But for any type of long distance still switch to the bike.

Anyways, is there any reason why a 24 cell..24s?...60v system with lifepo4 batteries is a bad idea? Only see people talking about 6-12s batteries using lipo.

Am thinking about 2 long battery tubes moulded into each side of the deck, 4 tubes in total holding 12 14500 cells each. Will turn these tubs out of aluminum and make it so the batteries fit in tightly so that there is no slop. Much like a mag lite there would be a screw top with a strong spring to hold all the batteries in contact with each other.

Have read that it is best to solder the leads for the most reliable battery pack, and wonder if there is any good way to solve this, because it would be nice to be able to take out cells as needed.

Maybe I'm living in a dream world? :roll:
 
Nice board. I'm not to familiar with batteries compared to others but 24S is a lot of voltage that should probably be handled with someone with experience.

We also don't necessarily need all that power on a board. You could wire it up in parallel since 12S is about all we would need IMO.

Can't wait to see your build :) sounds like a great idea. I would like to connect 18650's or 26650 - LiNCM or LiFePO4 cells.
 
Thanks torque!

Fair enough, experience is definitely not on my side so far as batteries go!

Had looked at 18650's as well, but they would be quite a lot harder to fit into a deck at 30+mm in diameter.
